While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique ...

The main difference between prokaryotic and eukaryotic cells lies in their structure. Prokaryotic cells and eukaryotic cells are the two types of cells that exist on Earth. There are several ...

Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi.

Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament. A ...

Pili are short, hair-like structures on the cell surface of prokaryotic cells. They can have a role in movement, but are more often involved in adherence to surfaces, which facilitates infection, and ...

All living organisms are made up of cells. It is the basic, structural, and functional unit of life. Also, it is known as "Building blocks of life". Cell biology is the study of cells. It consists of ...
